With the construction of the jubilee line extension, the opportunity was taken to introduce new trains, and today the line is worked by 1996 stock, which has an exterior similar to the 1995 stock in use on the northern line but (in spite of the confusing naming) is technically less advanced.

It is probably one of those places in which one could justify an underground station, if one happened to be building a line through it (something bermondsey benefited from on the jubilee line) but it would be very difficult to make a case of building a line specifically to serve it.
